R9 285 Crossfire + VSync Audio Popping/Stuttering

Refer to the following thread for an in-depth detail of the on-going problem:
Basically this is somewhat of a common problem with the R9 series of GPUs. As it has all been heard before I'll keep it short and sweet. I'm here to keep the problem in light and hopefully be just another one to nudge AMD to actually do something.


The issue: When attempting to use dual monitors in an R9 Crossfire setup, if Crossfire is enabled and you attempt to run a Fullscreen game/application with VSync enabled, audio distortion (popping/stuttering/cutting in and out and video lag/stuttering occurs. The only ways around it are:
A) Disable Crossfire (Rendering a Crossfire setup pointless)
B) Disable V Sync for nausea-inducing tearing on my monitor or TV (60Hz).
C) Switch to Windowed or Borderless Window in the program. In which case the Audio stuttering and Video lag stops simultaneously on a dime. Even with Crossfire and V Sync enabled. Hooray! Sort of.

However, there are many games that I wish to play Fullscreen as I currently enjoy streaming:


Here is a video demonstration of the problem.


The question: As this has been an ongoing problem apparently since 2013, is there any RECENT update or viable work-around for this KNOWN issue? Other than option C?
The issue, for me, has been ongoing since I got my new build in April 2015 and since I first hooked up dual monitors, attempting to play PC games on one. So technically, on all of the drivers that have released since then (I love to stay up to date. And obviously, naïve enough to think this would get fixed any time soon...) I am currently running the 15.10 beta as the WHQL are no better.

I have My ASUS VX248 hooked up via DVI and TV as the primary via HDMI, but it doesn't matter what displays I use. Also tried the laptop as a display. The audio popping also occurs with any audio device, headphones, monitor, tv, other headphones etc.


It has been a long road of migraines and hair pulling. At first I thought it was OBS, then I thought it was my headphones, then I tested every audio source and audio device possible, then I realized it only did it with crossfire. Then after a Google search I was able to narrow it down to Crossfire + VSync. I also found threads and forums dating back to 2013 and AMD either keeping their heads down, denying it, or claiming it has been 'fixed' and yet here we are at the end of 2015. Quite despicable, really. So lastly, I found this problem was quite common, in fact.


I'd rather skip the theatrics. Have you tried disabling your unused audio devices/onboard audio? Yes. Have you tried testing each card? Yes they work fine. Blahblahblah

I, like most others with this problem, have literally tried everything possible, from messing around with simple Windows settings, to closing all un-needed applications and down to disabling everything I did not need in Device Manager to see if I could narrow it down further.
Absolutely nothing. There is obviously some sort of driver issue on AMDs end that they refuse to acknowledge and fix.


I am VERY close to selling both cards and getting a single, more powerful card, as I am feeling a bit 'green' lately from all of this. If you know what I mean.
